FIGURE 2.

% of reporter cell control plating efficiency when cells are directly irradiated inside or outside a Faraday cage, or when medium is harvested from cells exposed inside or outside the cage. “IR” = ionizing radiation, “Recip” = recipients of irradiated cell conditioned medium. 0.5Gy irradiated or recipient cells were significantly different from unexposed cells (p<0.05), but were not significantly different from each other. 5.0Gy irradiated or recipient cells were significantly (p<0.01) different from unexposed controls. The Faraday cage did not significantly affect the plating efficiency of these groups.
